Carbon-coated aluminum foil refers to a composite foil material with a thickness of 1 μm, which is made of aluminum foil as the base and coated with adhesive and conductive materials on the aluminum current collector. Carbon-coated aluminum foil has the functions of enhancing coating bonding strength, reducing battery impedance, extending battery cycle life, and protecting current collectors. It is an important substrate for lithium batteries and is widely used in supercapacitors, power batteries, energy storage batteries and other fields.
